ABOUT CARBON PRICING UNLOCKED

T oday, about 40 national jurisdictions and over 20 cities, states, and regions are putting a price on carbon. Despite this global uptake,

harmonisation of carbon pricing policies across different regions remains difficult. Furthermore, carbon prices are often too low to incentivise the investment necessary to decarbonise emissions-intensive value chains. At the end-consumer level, the impact of carbon pricing is often insufficient to drive changes towards consumption of low carbon goods and services.

How can carbon pricing facilitate sustainable global economic growth? To find answers to this question, the Generation Foundation has teamed up with Ecofys in the Carbon Pricing Unlocked (CPU) research partnership. The research extends over three years from 2016 to 2019 and tackles carbon pricing from a new angle, exploring the role of carbon pricing along value chains up to the end-consumers. The partnership aims to deliver quantified insights into the role carbon pricing can play in a 1.5°C future.

Ecofys is one of the pioneers in carbon pricing, and has worked on the topic for nearly two decades. The Generation Foundation is the advocacy initiative of Generation Investment Management LLP, which was co-founded by Al Gore and David Blood in 2004, and works on the decoupling of prosperity from resource-intensive growth. Combining in-depth expertise with a high-level stakeholder network, Ecofys and The Generation Foundation investigate how carbon pricing might be better integrated at an economic policy level in order to unlock its full mitigation potential.

For this first output under the CPU partnership, Ecofys and the Generation Foundation worked together with the Norwegian University of Science and Technology and PBL Netherlands Environmental Assessment Agency.

T he 2015 Paris Agreement and its subsequent policy implications are pivotal steps for mankind in its effort to combat climate change. For the

first time in history, all Parties to the United Nations Framework Convention on Climate Change (UNFCCC) have committed to take action to limit global warming. According to UN Secretary-General Ban Ki-moon this momentum highlights “the urgency for action, and reflects the consensus of governments that robust global cooperation, grounded in national action, is essential to meet the climate challenge.” 1

With the Paris Agreement now in force, the attention is shifting to implementation. While the various Nationally Determined Contributions submitted by countries diverge in their foreseen climate change strategy, about two-thirds of the national pledges refer to carbon pricing as one of the measures to reduce greenhouse gas (GHG) emissions. Carbon pricing internalises the costs of climate change, making it part of the economic decision-making process. Carbon pricing thus has the potential to facilitate the decarbonisation of global value chains enabling sustainable economic value creation and growth.

Carbon pricing discussions often take a simple “vertical” view through a specific jurisdiction, company, or sector. However, climate change is a global issue with impacts across all jurisdictions, all companies and all sectors. In this study we provide a “horizontal” perspective on how carbon pricing affects global value chains across regions and sectors. We analyse GHG productivity: the ratio between the economic value created and GHG emissions along each stage in global value chains.

The GHG productivity, defined as the value created per unit of GHG emitted, ranges from US$0.2–3.6/kgCO2e for the consumption categories studied. The global average GHG productivity equals US$1.7/kgCO2e. The wide range is attributed to the diversity of the value chains in different sectors. Assuming a global carbon price of US$100/tCO2e, consistent with scenarios to limit global warming to 2°C, we derive the value at stake for the goods and services we consume, grouped by consumption category. The value at stake ranges from 3% for the consumption of medical care, public and other services to as high as 59% for the use of fuels for space heating and cooking.

Carbon pricing raises revenues for governments through taxes and allowance auctions. These revenues can be recycled back into the economy. Assuming that carbon pricing revenues are redistributed into the economy in proportion to the value created, we calculate the impact that global carbon price could have on consumer prices. A global carbon price could make consumption of services 3% cheaper, whereas consumption of material products (shelter and construction, clothes, furniture and appliances) as well as food consumption could become up to 3% more expensive. The average potential price increase for mobility is around 5%, the potential price increase for electricity and fuel use could be 50%. All these estimates are static and theoretical, assuming no value chain response in terms of uptake of GHG emissions abatement, no consumer behaviour responses, and no differentiation in carbon prices applied by region. The estimates nonetheless illustrate how different value chains are affected by a global carbon price.

EXECUTIVE SUMMARY

5

What does this analysis imply for the design of effective carbon pricing policies? Our main findings can be summarised as follows:

1. A global carbon price is unlikely to cause major shifts in consumption patterns between materials, food and services. This is due to the typically low price responsiveness of consumption in combination with modest price impacts due to carbon pricing.

2. In the value chains related to the consumption of materials and food, emissions occur upstream, whereas value creation happens more downstream. Carbon pricing is well suited to provide the necessary incentives to decarbonise lower GHG productive mining and manufacturing processes upstream given that these sectors compete on costs.

3. Governments often combine carbon pricing with measures to avoid negative impacts on industrial competiveness. As a result, the carbon price is not always passed on in the value chain and does not incentivise lower GHG emissions downstream.

4. The horizontal lens applied in this research reveals the need for carbon pricing approaches that incentivise higher GHG productivity throughout full value chains. Possible examples include a GHG consumption charge based on the material content of consumer goods, a carbon added tax or globally applied sectoral carbon pricing approaches for key industrial commodities.

5. For the consumption of food, clothing, furniture and appliances, large consumer-facing companies could play a role of “aggregators of GHG emissions” in their supply chain. At these companies, internal carbon pricing approaches, not only focused on the companies’ own emissions, but also on the supply chain emissions could play a role to incentivise decarbonisation throughout the supply chain. This is a topic we aim to address in the next phase of the CPU partnership.

6. For shelter and construction, a point to note is the important role of the public sector. Public entities could further step up in requiring the construction supply chain to disclose information on GHG productivity and use a carbon price as part of public procurement procedures or to create funds that could be re-invested in the supply chain to increase its GHG productivity.

7. Notable exceptions to the pattern of relatively modest impacts of carbon pricing on end-consumer prices are the consumption of electricity, the use of fuels for space heating, cooking, as well as our mobility. The low average GHG productivity of these often short and to a large extent localised value chains make them attractive candidates for the application of carbon pricing policies to drive decarbonisation.

8. For carbon pricing to cost-effectively support decarbonisation, it is essential that competing technologies fulfilling the same need all face a similar carbon price. This is an important implication for the design of carbon pricing policies resulting from the horizontal value chain lens applied in this research.

9. Income distribution effects resulting from carbon pricing policies need sufficient attention. A targeted revenue recycling approach could be used to compensate for price increases affecting certain low income or otherwise vulnerable groups and to enhance the impact of the policies. We intend to study revenue recycling models in more depth in the next phase of the CPU partnership.

conception to its end use and beyond. The activities that comprise a value chain can be contained within a single firm or divided among different firms.

S upport for carbon pricing policies is growing worldwide given the urgency to reduce greenhouse gas (GHG) emissions. As of October

2016, 40 national jurisdictions and over 20 cities, states, and regions are putting a price on carbon - representing about 13% of global GHG emissions.2 Furthermore, over 1,200 businesses currently price their carbon emissions or intend to do so in the next two years to manage the risks associated with climate change.3

The entry into force of the Paris Agreement will further increase the momentum behind carbon pricing. While countries diverge in the policies they plan to apply, about two-thirds of the submitted national pledges for climate action refer to carbon pricing as a measure to tackle GHG emissions. New schemes are set to be introduced in China and Canada, amongst other countries. Declining oil, gas and coal prices over the past years have also provided a window of opportunity for policymakers and businesses to price carbon.4

Carbon pricing places a price on the external costs of GHG emissions. This allows these costs to be factored into total production costs and thus to become part of the economic rationale for actors taking investment decisions. GHG emissions are emitted as part of activities where economic value is created, and as such, carbon pricing has the potential to facilitate the decarbonisation of global value chains5 while enabling sustainable economic value creation and growth.

There are different forms of carbon pricing, including emission trading systems (ETSs)—both cap-and-trade and baseline-and-credit systems, carbon taxes, offset mechanisms and results-based climate finance mechanisms that use emission reductions related metrics. For governments, ETSs and carbon taxes are the main instruments. Over the last decade the difference between these two types of instruments has become less distinct. Several ETSs, including the Regional Greenhouse Gas Initiative in Northeast and Mid-Atlantic States of the United States and the New Zealand ETS, have included fixed price elements. Alternatively, carbon taxes can incorporate the use of credits, such as the proposed South African tax. Besides governments, companies can also set an internal carbon price or shadow price to facilitate decision-making toward more sustainable operations. More recently, the UN’s specialised aviation body—the Internal Civil Aviation Organization—has shown carbon pricing can be imposed on a complete sector, setting up a global offset mechanism to ensure international aviation follows a carbon-neutral growth trajectory.

The above examples illustrate that carbon pricing is often looked at through a “vertical” lens, either focusing on a specific jurisdiction, company or sector. However, climate change is a global issue with impacts across all jurisdictions, all companies and all sectors. The Paris Agreement recognises the cross-cutting nature of climate change and provides the impetus for countries, companies and sectors to limit the global temperature increase to 2°C, with the ambition of 1.5°C.

is created. How does this figure compare to the targets set out by the Paris Agreement? Assuming a global GDP growth of 3%7 per year until 2050, and required emission reductions of 40 to 70%8 compared to 2010 to keep global warming below 2°C, a global GHG productivity of around US$9-18/kgCO2e is needed by 2050. This means that global GHG productivity needs to increase by 4-6% each year to meet a 2°C target and even more for a 1.5°C target. There is thus an enormous need to decouple economic value creation from global GHG emissions.

Carbon pricing supports this increase in GHG productivity. It facilitates decision making towards production methods by producers as well as the end-consumption of goods and services (assuming cost pass-through) with relatively high value creation in relation to GHG emissions. For example, a carbon price could lead to more lightweight materials in products or consumers favouring a diet with less meat. The options are endless, raising multiple important questions. Where does carbon pricing work? Where is it most needed? What will be its impact? This report provides some answers to these questions.

In Chapter 2 of the report, we present the methodology we used in our research. In Chapter 3, we provide a global overview of global GHG emissions and value creation in the form of a global GHG productivity map. In Chapter 4, we then zoom in on specific consumption categories before drawing overarching conclusions on the implications for carbon pricing design in Chapter 5.

In this study, we provide a more “horizontal” perspective to these discussions, by looking at global value chains with the ultimate objective to provide insights in and support the design of more effective carbon pricing policies (see Figure 1). For example, we look at global food, mobility and service value chains to identify where value is created efficiently in relation to GHGs emitted.

The term “GHG productivity” is defined to describe this relationship, and represents the amount of value created per unit of GHG emitted. With global gross domestic product (GDP) approximately US$70.1 trillion and global emissions amounting to 41.6 GtCO2e,6 the global average GHG productivity is US$1.7/kgCO2e. In other words, for every kilogram of CO2-equivalent emissions emitted worldwide, US$1.7 of economic value

11 Using the six main greenhouse gases under the Kyoto Protocol: CO2, CH4, N2O, HFCs, PFCs, SF6. These are then converted to CO2e emissions using the global warming potential of 100 years from the IPCC (2007). Use-phase emissions from households are included, but emissions from land use, land-use change, and forestry are excluded as these are difficult to allocate to economic activity.

12 In this analysis we use GDP nominal and not purchasing power parity as regions in this analysis are aggregated.13 Various final end-consumption categories, including household and government consumption and capital

formation have been aggregated to one final demand category.

Linking GHG emissions and value creation through input-output analysis

In this research, we make use of input-output (I/O) analysis. I/O analysis depicts inter-industry relationships within an economy. It describes how the outputs from one sector of the economy become the inputs for other sectors of the economy. At the core of I/O models are input-output tables, representing trade flows between sectors within one region, and relating these flows to the final consumption of goods and services within a region. As the scope of our research is global, we have used a multiregional input-output model (MRIO), which also includes inter-sectoral trade flows between regions. MRIO models provide detailed insights into how the global economy is structured. The theoretical foundation of I/O analysis was set in the first half of the twentieth century, and can be found in the early work done by Leontief.9

Ecofys was supported by the Norwegian University of Science and Technology (NTNU) and PBL Netherlands Environmental Assessment Agency (PBL). NTNU is a leading research institution on I/O and is one of the co-founders of the I/O-database used in this study (EXIOBASE 3).10 NTNU assisted in data retrieval and interpretation of the results, and reviewed the report.

PBL is the Dutch national research institute in the fields of the environment, nature and spatial planning, and conducts strategic policy analyses on request of several Dutch ministries. PBL was involved in setting-up this study, interpreting the results, and critically reviewing the work done throughout the research.

We approach the relationship between GHG emissions11 and value creation12 in value chains in three different ways:

» Source perspective: we look at where emissions occur in the various value chains, and how these emissions relate to the creation of value at that point of the value chain.

» Value chain perspective: we allocate the full value chain emissions to the final demand13 for goods and services that sectors deliver to private and public consumers and link this to the value of the goods and services delivered to these end-consumers. Annex I provides an overview and definition of the sectors distinguished.

» Consumption perspective: we allocate these value chain emissions to the specific consumption categories given in Figure 3 to make the link to the needs of end-consumers.

Annex II provides a definition of the consumption categories distinguished.

10

Figure 2 provides an overview of how these three approaches are related. Figure 5 in the next chapter of this report is built on these perspectives, showing a global overview of GHG emissions and value creation.

Despite extensive research on embedded emissions in consumption and trade, few studies make the explicit link from the GHG emissions in value chains to value creation.14 Our study draws this link. This study also systemically attributes all global GHG emissions to end-consumption categories, and links this to the economic value created along the value chain.

Calculating GHG productivity of global value chains

In designing carbon pricing policies for global value chains, it is essential to understand the different characteristics of these value chains. In the context of carbon pricing, an important parameter is the ratio between value creation and GHG emissions. To study this ratio, we define a new metric: “GHG productivity” expressed as the value created in US dollars16 per kg of CO2 equivalent emissions (US$/kgCO2e). GHG productivity

14 Exceptions include studies published by PBL Netherlands Environmental Assessment Agency on embodied emissions and value added for different sectors in the Netherlands and by Stanford Center for International Development on trade in global value chains and embodied emissions.

15 Strictly speaking, fuel and electricity use are no separate consumption categories, but fulfil needs covered by other consumption categories such as a heated home (shelter and construction) or functioning appliances (furniture and domestic appliances). Given their importance in the GHG footprint of consumption, we decided to show them separately.

16 As EXIOBASE 3 provides the value added in euros, we converted euros to US$ using the annual average exchange rate for the year 2011 of 0.719424 (rounded). This number is taken from the online statistics database (www.statista.com) that uses data on the euro to US$ exchange rate from the European Central Bank.

17 Here value added includes taxes, trade and transport margins in the purchased products (e.g. freight is included in the price of a book). While for modelling purposes it is important to use basic prices, we re-classify consumer expenditure on trade and transport margins to the corresponding good to show the impact by the actual purchased product. A description of the methodology (but employed in reverse here) can be found in Ivanova et al, 2016, “Environmental Impact Assessment of Household Consumption”. Journal of Industrial Ecology.

is derived from the results of the I/O analysis. A global value chain with a high GHG productivity creates more value per kilogram of GHG emissions than a global value chain with relatively low GHG productivity. We use GHG productivity to highlight the opportunity to sustain economic value creation with lower GHG emissions.

Value at stake and impact on consumer prices: implications for carbon pricing design

By approaching value chains in three different ways and looking at their GHG productivity, we are able to point to parts of value chains where carbon pricing has significant potential as a tool to drive decarbonisation. To determine the impacts of carbon pricing on the value chain, we define the “value at stake”. This equals the amount of GHG emissions divided by the value added17, multiplied by a carbon price. We apply a carbon price equal to US$100/tCO2e, which is consistent with the estimate used by both the Intergovernmental Panel on Climate Change (IPCC)18 and the International Energy Agency (IEA)19 in their 450ppm scenarios that are in line with the goal to limit global warming to 2°C.

Carbon pricing raises revenues for governments that can be recycled back into the economy. To calculate the impact a carbon price could have on consumer prices,

we apply a simple carbon pricing revenue recycling approach by assuming revenues are recycled into the economy in proportion to the value created. Finally, by combining the quantitative results with qualitative insights in the value chains and insights from the assessment of carbon pricing policies already in place around the world, we arrive at conclusions on the implications for the design of carbon pricing policies.

It is important to note that all our estimates are static and theoretical, assuming no value chain response in terms of uptake of GHG emissions abatement, no consumer behaviour responses, and no differentiation in carbon prices applied by region. However, the estimates can nonetheless serve as a proxy to understand the implications of a global carbon price on consumers.

Expert consultation

The interim findings of the research were presented at an expert workshop convened by Ecofys, the Generation Foundation, NTNU and PBL. The workshop, which took place in July 2016, gathered experts from academia, foundations, not-for-profit organisations and the private sector. The purpose was to gather inputs from a wide range of stakeholders on the research and its implications for carbon pricing.

Our approach is summarised in Figure 4.

T his chapter provides an overview of the link between GHG emissions and value creation. This information is provided in a global GHG

productivity map (see Figure 5). This map shows the relationship between GHG emissions and value creation in global value chains using the three perspectives as described in Chapter 2.

Source perspective: » The left part of the diagram shows where emissions

occur in the value chain, and how these emissions relate to the creation of value by a specific sector.20

Value chain perspective: » The flows from the left to middle part of the diagram

represent embodied emissions in products traded between sectors.

» The middle part of the diagram represents the emissions associated with goods and services delivered by a specific sector for end-consumption.21

Consumption perspective: » The flows from the middle to right part of the

diagram represent a reclassification of goods and services to various consumption categories.22

» The right part of the diagram represents the emissions associated with various consumption categories.

The flows and bars in the diagram represent GHG emissions, where the width is proportional to the amount of GHG emissions. The colours depict GHG productivity, where green denotes high GHG productivity and red low GHG productivity. All colours in between denote medium GHG productivities (see the scale above Figure 5).

To illustrate this diagram, consider the following practical example. The electrical, machinery, metals and manufacturing sector (left) delivers the product steel to the construction sector (middle), which is used to construct houses. These houses are used as shelter. Hence, all emissions and value associated with this value chain is in the end assigned to the consumption category shelter and construction (right).

A number of key results are summarised for each consumption category in Table 1. The next chapter zooms in on each of the eight consumption categories presented on the right part of the diagram. It provides more detailed descriptions of these global value chains and discusses implications for carbon pricing policy design.

20 In GHG emissions accounting, this is often referred to as “production-based accounting”. This is the accounting method currently used under the UNFCCC, and is sometimes criticised for not including international transportation and carbon leakage, see e.g. Peters (2008) – From production-based to consumption-based national emission inventories.

21 In GHG emissions accounting, this is often referred to as “consumption-based accounting”. 22 No input-output calculation takes place at this step. Instead, GHG emissions are reallocated to consumption

categories.

17 Carbon pricing implications for final consumption categories

FUEL USE FOR HEATING AND COOKING

GHG productivity: 0.2 US$/kgCO2e

Share in global consumption value: 0.5%

Share in global GHG emissions: 5.1%

Sectors contributing most to value chain GHG emissions: use-phase emissions (64%), electricity, gas and water (17%), mining and quarrying (16%)

Sectors contributing most to value creation in the value chain: mining and quarrying (55%), petroleum, chemicals and non-metallic minerals (17%), service sectors (17%)

Value at stake and price impact using a global carbon price: 57% and 51%

» Emissions along the value chain: The majority of the value chain emissions occur at the end-consumer in the form of use-phase emissions when fuels are used for e.g. heating.

» Key characteristics of the value chain: › The value chain is short and international due to trade in fossil

fuels, but very much localised in terms of the final product being mainly space heating and cooking.

› Technologies with a higher GHG productivity compared to fossil fuel use include the use of bio-fuels and technologies replacing fuel use by renewable electricity (e.g. using heat pumps) or technologies reducing overall fuel use (e.g. better insulation).

› Decarbonisation of this value chain will induce a shift in value creation from the fossil fuel industry to the renewable electricity and advanced manufacturing sectors.

» Implications for carbon pricing: › Some jurisdictions already apply a carbon price to domestic fuel

use, either in the form of a carbon tax or via emissions trading with the point of obligation at the fuel delivering entities.

› For carbon pricing to adequately incentivise the decarbonisation, it is essential that both high and low GHG productive technologies fulfilling the same need are covered by carbon pricing in order to incentivise the higher GHG productive alternatives.

› For example, if electricity production is under a carbon price policy, but fuel use by end-consumers is not, consumers have a lower incentive to choose the higher GHG productive solution (electricity based heat pumps) compared to the lower GHG productive alternative (the use of fossil fuels for space heating).

› A further point of attention in the design of effective carbon pricing policies for this value chain is the integration of carbon pricing with existing energy taxation policies, e.g. by making (part of) the energy taxation dependent on the CO2 content of the energy used.

18 Carbon pricing implications for final consumption categories

ELECTRICITY USE

GHG productivity: US$0.2/kgCO2e

Share in global consumption value: 0.8%

Share in global GHG emissions: 7.5%

Sectors contributing most to value chain GHG emissions: electricity, gas and water (93%), mining and quarrying (5%)

Sectors contributing most to value creation in the value chain: electricity, gas and water (57%), service sectors (17%), mining and quarrying (14%)

Value at stake and price impact using a global carbon price: 53% and 47%.

» Emissions along the value chain: Over 90% of value chain emissions are related to the burning of fossil fuels, often in large fossil power plants, with the rest of the emissions dispersed over sectors upstream

» Key characteristics of the value chain: › Similar to the final consumption of fuels, the value chain is

typically simple and short, international in terms of fossil fuel trade, but very much localised in terms of the production and delivery of the final product.

› There are large differences in GHG productivity in this category, especially between fossil and renewable electricity production.

» Implications for carbon pricing: › Differential GHG productivity between high and low-carbon

technologies confirms what can be seen in carbon pricing initiatives around the world: carbon pricing can be instrumental in achieving the required low carbon transition of the electricity value chain.

› Effectively, a global carbon price of US$100/tCO2e would undermine the business case for virtually all fossil based power generation. Such a carbon price would support renewable technologies and other low-carbon technologies.

› Given the low GHG productivity of fossil power production, it is no surprise that most jurisdictions with carbon pricing in place target the production of electricity, albeit with typically much lower prices than US$100/tCO2e.

› One of the reasons why the electricity sector is often targeted by carbon pricing is that emissions take place at typically large point sources where emissions can well be monitored.

› The experience of the EU ETS shows that consistently applied carbon pricing policies have the potential to impact investments in electricity generation technologies and the extent to which these technologies are used for power production

› A key challenge for carbon pricing is the degree to which electricity markets are liberalised, allowing carbon costs to be passed through the value chain.

› Carbon pricing can, as a result of the high value at stake, have a profound effect on end-consumer prices for electricity. It is therefore important to consider how affordable access to electricity can be guaranteed, especially for low income groups, through the targeted use of carbon pricing revenues.

19 Carbon pricing implications for final consumption categories

MOBILITY

GHG productivity: US$0.8/kgCO2e

Share in global consumption value: 8.0%

Share in global GHG emissions: 16.2%

Sectors contributing most to value chain GHG emissions: use-phase emissions (44%), electricity, gas and water (15%), transport sector (13%)

Sectors contributing most to value creation in the value chain: service sectors (33%), electrical, machinery, metals and manufacturing (24%), transport (21%)

Value at stake and price impact using a global carbon price: 12% and 6%.

» Emissions along the value chain: Emissions at the point of consumption (e.g. road transport fuels) contribute 44%, emissions in the electricity, gas and water as well as the transport sector itself (including aviation) 28% with the remaining emissions dispersed over the various supplying industries such as transport equipment.

» Key characteristics of the value chain: › The length and degree of internationalisation of mobility differ

between the various mobility value chains delivering goods for final consumption.

› Material intensive consumption items such as cars and other transport equipment are characterised by long, diverse and international value chains, whereas the value chains related to transport fuel deliveries are short and very much localised.

» Implications for carbon pricing › The current application of carbon pricing in the mobility value

chain remains minimal at best, with carbon pricing being applied to transport fuels and domestic aviation in only a few jurisdictions. The aviation sector recently agreed on an offset based market mechanism that will start operation in 2021.

› For carbon pricing to incentivise a modal shift from low GHG productive transportation means (e.g. fossil-fuels based cars, short distance aviation) to higher GHG productivity transportation means (e.g. public transport, electric cars), it is important that a consistent carbon price is applied to competing technologies that fulfil the same need, in this case to all different transport modes, either in the form of a tax, or an ETS.

› Arguably, global carbon pricing could have some effect on consumer prices for the aviation sector. The recently agreed global mechanism for the aviation sector will make use of offsets generated outside of the sector to facilitate cost-effective mitigation.

20 Carbon pricing implications for final consumption categories

FOOD AND TOBACCO

GHG productivity: US$1.1/kgCO2e

Share in global consumption value: 8.2%

Share in global GHG emissions: 12.7%

Sectors contributing most to value chain GHG emissions: agriculture, hunting, forestry and fishing (53%), electricity gas and water (17%), food production, beverages and tobacco (8%)

Sectors contributing most to value creation in the value chain: agriculture, hunting, forestry and fishing (32%), service sectors (28%), food production, beverages and tobacco (24 %)

Value at stake and price impact using a global carbon price: 9% and 3%.

» Emissions along the value chain: The emissions from food consumption are dominated by emissions from agriculture. Compared to other consumption categories, non-CO2 emissions represent a significant share of the overall emissions.

» Key characteristics of the value chain: › The value chains related to food consumption are diverse,

ranging from short local food production and consumption chains to complex, long international value chains with many actors involved, depending on local circumstances and income levels.

› There are significant differences between the GHG productivity of different food value chains with vegetable products, and drinks and tobacco having a higher GHG productivity compared to meat, fish, and dairy products. This results from differences in, inter alia, inputs and efficiency as well as in the number of processing steps.

» Implications for carbon pricing › Given the differences in GHG productivity between value chains,

carbon pricing has the potential to incentivise a shift from less to more GHG productive diets. This potential is hampered by the dispersed nature of where the emissions take place, the relatively high share of methane and N2O emissions that are difficult to measure and the relatively low impact on consumer prices.

› For these reasons, carbon pricing is currently seldom applied to the emissions related to this consumption category with the exception of the emissions related to the electricity consumed in the supply chains.

› Downstream, the food consumption value chain is dominated by large consumer-facing food processing and retail stores, especially in high income countries. It is worthwhile to explore further the role these companies could play as “aggregators of GHG emissions” in their supply chain. Internal carbon pricing approaches, not only focused on the companies’ own emissions, but also on the supply chain emissions could play a role to incentivise decarbonisation throughout the supply chain.

FURNITURE AND HOUSEHOLD APPLIANCES

GHG productivity: US$1.5/kgCO2e

Share in global consumption value: 11.8%

Share in global GHG emissions: 13.6%

Sectors contributing most to value chain GHG emissions: electricity, gas and water (34%), electrical, machinery, metals and manufacturing (22%), petroleum, chemicals and non-metallic minerals (14%)

Sectors contributing most to value creation in the value chain: electrical, machinery, metals and manufacturing (36%), service sectors (32%), petroleum, chemicals and non-metallic mineral products (11%)

Value at stake and price impact using a global carbon price: 7% and 1%.

» Emissions along the value chain: The value chain emissions are dominated by electricity related emissions and emissions related to the manufacturing and processing of materials, together responsible for as much as 83% of the value chain emissions.

» Key characteristics of the value chain: › These material value chains are typically long, consisting of

many different processing steps, and very international with basic (industrial commodities such a steel that end up in our appliances), intermediate (semi-manufactured parts) and final products (the appliances itself) being traded all over the world.

› The GHG productivity of the upstream material production industries is low, and as a result, the impact of carbon pricing high. Given the cost-competitive characteristics of these production processes, carbon pricing therefore provides a strong incentive for decarbonisation of the production process itself.

» Implications for carbon pricing › Many of the existing carbon pricing schemes in the world include

significant parts of these upstream material production and processing industries.

› One reason for the inclusion of these upstream industries in carbon pricing schemes is that these emissions often occur in facilities with large point sources of emissions that are relatively easy to monitor.

› Carbon pricing policies are often combined with measures (either in the form of free allocation in an ETS or in the form of tax free thresholds) to avoid a loss of competiveness for domestic industries, resulting in a risk of carbon leakage.

› As a result, carbon prices are not fully passed through the supply chain and do not provide an incentive for downstream material efficiency.

› Global, sector-based approaches as well as carbon taxes applied at the level of consumption (including taxation at the border based on the carbon content of goods) are alternative carbon pricing models that could ensure incentives for full value chain decarbonisation, albeit that the feasibility of such policies needs further assessment.

CLOTHING

GHG productivity: US$1.5/kgCO2e

Share in global consumption value: 1.9%

Share in global GHG emissions: 2.1%

Sectors contributing most to value chain GHG emissions: electricity, gas and water (39%), agriculture, hunting, forestry and fishing (18%), textiles, leather and wearing apparel (12%)

Sectors contributing most to value creation in the value chain: textiles, leather and wearing apparel (41%), service sectors (29%), agriculture, hunting, forestry and fishing (7%)

Value at stake and price impact using a global carbon price: 7% and 1%

» Emissions along the value chain: The value chain emissions originate in the agricultural value chain (leather, cotton), the material manufacturing industry as well as in the final processing industry producing the final products for consumption.

» Key characteristics of the value chain: › Value chains are typically long and international, with a significant

share of emissions originating in low income countries, e.g. in textile production. Non-CO2 emissions represent a significant share of the value chain emissions.

› Clothing and footwear represent a relatively minor share of both global value creation and global GHG emissions (2%).

» Implications for carbon pricing: › Carbon pricing is used to a very limited extent to GHG emissions

in this value chain. Similar to the food sector, the dispersed nature of the emission sources and the relatively low impact on prices throughout the value chain hampers the impact of carbon pricing

› Downstream, the clothing value chain is dominated by large consumer-facing clothing brands, especially for high income countries. Similar to the food sector, it is worthwhile to explore further the role internal carbon pricing could play in clothing sector companies to incentivise decarbonisation throughout the supply chain.

23 Carbon pricing implications for final consumption categories

SHELTER AND CONSTRUCTION

GHG productivity: US$1.8/kgCO2e

Share in global consumption value: 22.3%

Share in global GHG emissions: 21.2%

Sectors contributing most to value chain GHG emissions: petroleum, chemicals and non-metallic minerals (32%), electricity, gas and water (28%), mining and quarrying (11%)

Sectors contributing most to value creation in the value chain: service sectors (51%), construction (24%), electrical, machinery, metals and manufacturing (7%)

Value at stake and price impact using a global carbon price: 6% and 0%.

» Emissions along the value chain: About 50% of the value related to shelter and construction is generated downstream in the real estate and other service sectors, whereas the vast majority of the GHG emissions originate from low value added, highly emission intensive upstream material production processes.

» Key characteristics of the value chain › The shelter and construction sector represents slightly over a

fifth of global value creation and GHG emissions. › Cement, lime and plaster production alone are responsible

or about a quarter of the emissions related to shelter and construction.

› The shelter and construction sector is local by definition, with the final products being fixed localised assets. Value chains are often relatively short.

» Implications for carbon pricing › The GHG productivity of the upstream material product and

production industry is low. As a result, the impact of carbon pricing on product prices upstream is high, providing strong incentives for decarbonisation. This explains why many of the existing carbon pricing schemes around the world cover significant parts of these material production and processing industries.

› As discussed under the furniture and domestic appliance consumption category, the carbon pricing policies are often combined with measures to avoid a loss of competiveness for domestic industries and minimise the risk of carbon leakage. As a result, carbon prices are not fully passed through the supply chain.

› Global, sector-based approaches and consumption based taxation at the border mentioned above are alternative carbon pricing models that could provide full value chain decarbonisation incentives in the shelter and construction value chain.

› For the shelter and construction consumption value chain, a further important characteristic is the important role of the public sector. Public entities in charge of construction decisions could further step up in requiring the construction supply chain to disclose information on GHG productivity and use a carbon price as part of public procurement procedures or to create funds that could be re-invested in the supply chain to increase its GHG productivity. This is becoming more and more important because supply chain emissions of buildings become relatively more important as use-phase emissions decrease as a result of, for example, insulation.

24 Carbon pricing implications for final consumption categories

EDUCATION, MEDICAL CARE, PUBLIC AND OTHER SERVICES

GHG productivity: US$3.6/kgCO2e

Share in global consumption value: 46.3%

Share in global GHG emissions: 21.6%

Sectors contributing most to value chain GHG emissions: electricity, gas and water (35%), service sector (25%), agriculture, hunting, forestry and fishing (10%)

Sectors contributing most to value creation in the value chain: service sectors (85%)

Value at stake and price impact using a global carbon price: 3% and -3%

» Emissions along the value chain: It is dispersed in terms of the sectors contributing to GHG emissions, but emissions resulting from the consumption of electricity and fuels by the sector itself represent a significant share of the emissions.

» Key characteristics of the value chain › The final consumption of a variety of services now represents

already close to 50% of global consumption, but only slightly over 20% of global GHG emissions.

› Value chains are typically short and local.

» Implications for carbon pricing › Carbon pricing is seldom applied in this value chain, except for

the electricity consumed in this supply chain. › The low price impact and relatively low price responsiveness

of the service related value chains make it unlikely that carbon pricing will have a direct impact on the decarbonisation of this sector at the end-consumer level.

› Instead, effective carbon pricing design for the electricity sector as well as for the building-related emissions, discussed above, will support the decarbonisation of this consumption category.

INSIGHTS FOR EFFECTIVE CARBON PRICING DESIGN

5

C arbon pricing internalises the costs of climate change and makes it part of the economic decision process. In this research we looked

at carbon pricing with a horizontal lens by focusing on global value chains from raw material extraction to final consumption. Our findings are summarised in Figure 6.

Through I/O analysis, we traced the origins of value creation in the value chains and source of GHG emissions, and assessed the GHG productivity of global value chains. The GHG productivity, defined as the value created by tonne of CO2 emitted, ranges from US$0.2–3.6/kgCO2e for the consumption categories studied. This wide range can be attributed to the diversity of the value chains in different sectors.

How does carbon pricing affect consumer prices in global value chains?

We derived the value at stake for the goods and services being consumed, grouped by end-use consumption categories, under a carbon pricing regime. A carbon price of US$100/tCO2e is assumed to be consistent with scenarios to limit global warming to 2°C. The value at stake ranges from 3% for the consumption of medical care, public and other services to as high as 59% for our use of fuels for space heating and cooking. These estimates do not consider the use of revenues raised by carbon pricing through, e.g. through the collection of carbon taxes or the auction of emissions allowances. Assuming that these revenues are redistributed into the economy in proportion to the value created, we calculated the impact that carbon pricing can have on consumer prices. It should be noted that our estimates are static and theoretical, assuming no value chain response in terms of uptake of GHG emissions abatement, no consumer behaviour responses, and no differentiation in carbon prices applied by region. However, the estimates can nonetheless serve as a proxy to understand the implications of a global carbon price on consumers.

Should carbon pricing be used if it does not impact consumer prices much?

Our analysis shows that highly GHG productive consumption of services could become 3% cheaper, whereas consumption of materials (shelter and construction, clothes, furniture and appliances) as well as food consumption could become up to 3% more expensive.

Given the typically low price responsiveness of consumption, this suggests that in contrast to global mobility and the use of electricity and fuels discussed below, carbon pricing might not lead to significant changes in consumption patterns for these consumption categories. This could suggest that carbon pricing should not be used at all in these sectors, but this is not necessarily the case.

In each of these value chains, large sources of GHG emissions can be detected upstream in the value chain that have a very low contribution to value creation. Downstream in the value chain, fewer emissions occur, but more value is created (see Table 2 for the shelter and construction category as an example).

These emissions intensive, low GHG productive upstream manufacturing processes are a natural candidate for inclusion in an effective carbon pricing scheme. These sectors are competing on costs, resulting in a high carbon price responsiveness. Given the large price impact of carbon pricing on these sectors, carbon pricing has the potential to induce change towards production technologies with a higher GHG productivity. This is recognised by most jurisdictions that implemented carbon pricing, with upstream material industries normally within the scope of their policies. However, another characteristic of at least some of these industries is that they compete in an international environment. Carbon pricing policy design in specific jurisdictions is therefore often combined with measures to avoid the negative impacts of carbon pricing on

industrial competiveness. As a result, the carbon price is not passed on in the value chain. Thus, while carbon pricing does incentivise a higher GHG productivity of production processes in the sectors covered, the price signal does not incentivise a higher GHG productivity more downstream. The horizontal lens applied in this research reveals the need for carbon pricing approaches that incentivise higher GHG productivity throughout full value chains, include those that involve cross-border trade. Possible examples include a GHG consumption charge based on the material content of consumption goods, a carbon added tax or globally applied sector carbon pricing approaches for key industrial commodities. These could be viable additions to more vertically applied carbon pricing approaches targeting mainly the upstream parts of these supply chains in combination with measures to avoid negative consequences on industrial competiveness.

Also, in the food, clothes, furniture and appliances sectors, large consumer-facing companies could play a role of “aggregators of GHG emissions” in their supply chain. These companies deliver final goods to consumers and often have significant power over parts of their supply chain. It is worthwhile to explore further the role of internal carbon pricing approaches in these large consumer facing companies. Approaches focused on the complete supply chain emissions could incentivise decarbonisation throughout the supply chain, even if the emissions in their supply chain are dispersed and spread over a large number of different point sources. This will be addressed in next phases of the CPU partnership.

For shelter and construction, it is important to highlight the role of the public sector. Public entities in charge of construction decisions could further step up in requiring the supply chain to disclose GHG productivity information and use a carbon price e.g. as part of public procurement procedures or to create funds that could be re-invested in the upstream supply chain to increase its GHG productivity. This is becoming more and more important because supply chain emissions of buildings become relatively more important as use-phase emissions decrease as a result of e.g. insulation.

27

What should be considered when designing carbon pricing policies that have a notable impact on consumer prices?

Exceptions to the pattern of relatively modest impact of carbon pricing on end-consumer prices are the consumption of electricity, the use of fuels for space heating and cooking and global mobility. The low average GHG productivity of these short and, to a large extent, localised value chains make them attractive candidates for the application of carbon pricing policies. Provided that producers in these value chains operate in markets where carbon costs can be passed through to the consumer, carbon pricing in these value chains has the potential to induce changes to higher GHG productive consumption. Examples include model shifts in transport, e.g. from private to public transport, and from planes to trains, as well as technology shifts, e.g. from fossil to renewable electricity, and from space

heating to better insulated homes. For this to happen, it is essential that competing technologies fulfilling the same need all face a similar carbon price. This could entail a revision in energy tax and excise duty used in many countries to include carbon pricing. This could ensure that carbon pricing is harmonised over different value chains that lead to the fulfillment of the same end-consumer needs. This is an important consideration for the design of carbon pricing policies resulting from the horizontal value chain lens applied in this research.

Given the potentially higher price impact of carbon pricing on these consumption categories, income distribution effects resulting from carbon pricing policies need sufficient attention. Above, we used a simple carbon pricing revenue model that recycles revenues in proportion to the value created, which could in practice be operationalised via lower income taxes. A more targeted revenue recycling approach could, however, be used to compensate for unwanted price increases for certain low income or otherwise vulnerable groups. Revenue recycling will be studied in more depth in the next phase of the CPU partnership.

25 The list of consumption categories has been constructed by the authors based on various examples in literature, e.g. Hertwich & Peters (2009) – Carbon Footprint of Nations: A Global, Trade-Linked Analysis; or Arto et al. (2012) – Global Resources Use and Pollution: Vol. I, Production, Consumption and Trade (1995-2008). The allocation of the 200 products and product groups in the I/O database to each of these consumption categories has been done manually by the authors using expert judgment.
